Efficient and simple cloth animation

Physical-based cloth modeling and animation is a hot topic in computer graphics. Recently the semi-implicit integration scheme has been widely employed in cloth animation because of its high stability. In this paper, we propose an efficient and simple iterative scheme to create realistic cloth animation. The linear system created in the semi-implicit scheme can be solved in approximately linear time complexity in one time-step. This greatly benefits real-time applications. We also improve the traditional mass-spring model by avoiding the shrink of the cloth model.
